M42 luftwaffe single decal helmet - please help

Hello,
I am looking at possibly purchasing this M42 SD Luft.
The seller wants $650 for it.
It has a nice shell but the liner is not so nice and the chinstrap broken/half missing.
I know that similar helmets in this condition seem to go for around this range but I am not an experienced German helmet collector (I mostly collect US helmets).
So I want to know if there is anything special about this one that would make it worth more or less?
Is $650 a reasonable price?

For me its a $450-500 helmet. Yes the liner looks as if its about to crumble, but to me that really is the only negative thing about it, and at least it's there! Here are the things that I do like about it;

1.) Nice textured paint with no surface rust
2.) Decal is 90% or better
3.) Full chinstrap (from what I can see)
4.) Liner is very rough but present with drawstring
5.) It's an M42 and they are my favorite

Overall in my opinion it is a very nice looking M42 except the liner. I'm sure they are getting harder to find by the day, with a decal in that shape. I would spend between $450-500 on this one. Definitely wouldn't be one you would want your kids to play with!
